What vessel supplies the vagina, vestibule, and vulva?
vaginal artery from internal pudendal artery
Describe Episiotomy
- incision through perineal body to access caudal vagina
- perineal position, anal purse string
- close in 3 layers: mucosa, muscle, and skin
What is a rectovaginal fistula?
communication between rectum and vagina
What are the clinical signs associated with congenital abnormalities of the vagina, vestibule, and vulva?
- vaginitis
- UTI
- painful bleeding
- hydrocolpos
What is septal stenosis?
- a form of vestibulovaginal stenosis
- band of tissue oriented dorsoventrally
- double vagina
How is septal stenosis treated?
- episiotomy
- mucosal resection at attachments
- laser ablation
What is vaginal edema/hyperplasia?
vaginal tissue becomes severely edematous and protrudes from the vulva
What is the typical signalment of vaginal edema/hyperplasia?
- large breed dogs
- < 2 years
- in proestrus or estrus
- very rare in cats
What is the history associated with vaginal edema/hyperplasia?
- protrusion of tissue from vulva
- discharge or hemorrhage from vulva
- breeding difficulties
- licking, dysuria, perineal enlargement
What is the medical treatment for vaginal hyperplasia/edema?
- keep tissue clean
- condition resolves at end of estrus
- GnRH or HCG will induce ovulation and shorten estrus
What is the surgical treatment for vaginal edema/hyperplasia?
- OVE will prevent recurrence
- healthy tissue: reduce, place mattress sutures across vulva, OVE
- damaged tissue: resect prolapsed tissue, OVE
Describe vaginal prolapse
- very rare
- entire circumference of vagina prolapses
- donut shaped appearance
How is vaginal prolapse treated?
- manual reduction and OHE
- place suture across vulva
What is the typical signalment for vaginal neoplasia?
- intact female dogs over 10 years
- rare in cats
What percentage of vaginal neoplasms are benign, and which are most common?
